YOKOTA AIR BASE, Japan — The U.S. military has ordered servicemembers in Japan not to buy or consume alcohol until further notice following a fatal vehicle accident involving a Marine on Okinawa.

U.S. Forces Japan commander Lt. Gen. Jerry Martinez ordered the ban after a vehicle driven by the Marine struck a minitruck at 5.30 a.m. Sunday, killing a 61-year-old Japanese man, said USFJ spokesman Capt. Tyler Hopkins.

The ban, which applies on and off base, came into effect Sunday evening and will remain in place until further notice, Hopkins said.

“Commanders across Japan will immediately lead mandatory training to address responsible alcohol use, risk management and acceptable behavior,” a USFJ statement said. All military members and U.S. government civilians in Japan are required to attend.
